Yes, you do have a bit of the situation there. But fear not, there is an answer at hand … actually, four answers:
1. Look for a linear fixture that has two feed points. Only one of them needs to go over the existing junction box. The other helps position the fixture over the table.
2. Look for a fixture with a very large or rectangular canopy. Or for a standard-canopy fixture, use a ceiling medallion in a 32-inch to 36-inch diameter.
3. Create an oval floating ceiling that is the same size or slightly smaller in dimension as the table. This could be made of MDF (medium-density fibreboard). It would hide the wiring coming from the original junction box, allowing new wiring to run to the center of the floating ceiling where the new pendant would be positioned. You could also run a perimeter of rope light along the top of the suspended ceiling, creating a soft glow and unifying this element to the original ceiling.
4. How about just moving the table over 16 inches?
